My LG Remarq phone's screen has gone black and I'm wondering if there is an easy fix. Something happened while I was making a phone call. It was fine when I started the call, but when I ended it, the screen was black. I've tried turning it on & off again and taking the battery out & putting it back in. Since I can't see the screen, I have no idea if there is a software update that I need to make or if there is somethiing that I can do to improve this.
